how to install Edit Email Subject (EES) to edit subject of received e-mails
I found on your website that I can edit subject lines of e-mails I received using the add on (https://support.mozilla.org/en-US/questions/1155148) .
I downloaded the add on, but unfortunately the
link 'how to install' goes to ? gets me a: Not Found . The requested URL was not found on this server. (http://xenos-email-notes.simplesite.com/416814616)
Since my computer does not know what to do with the downloaded file I need help on how to install the add on. Thanks

To install an addon that has been downloaded, - click tools>addons &themes (if using menu bar) or just 'addons*=&themes' if using hamburger menu. - click the gear wheel and select to install from file.
